Energy group exclusions are currently not supported

Hello,

I am trying to backmap a CG structure to an all-atom representation (Amber03).

When I run initram.sh, I get the following error:

```
ERROR 1 [file 1-EM.mdp]:
  Energy group exclusions are currently not supported
```

I think group cutoff is deprecated in the latest GROMACS, so I am not sure what to do. Any help would be greatly appreciated 

Thank you! :-)
